IMPROVEMENT 1N FEED-ATTACHMENT 'Fon MACHINERY.

The Scheulo referre to .in these Letters Patent and making part nf the same.

To all whom it may concern,

Be it known that I, SAMUEL BROWN, of Philadelphia, in thecounty of Philadelphia, and State of Pennsylvania, have invented a new and improved Feed-Attachment for 4Machines, and -'I do hereby declare that the following is a full, clear, and'v exact description thereof, which will enable those skilled -in theart to make and use the same, reference heilig had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional elevation of my invention, the

section being taken through the line :v :c of lfig. 2.

Figure 2 is a top view-of a part ofthe feed-mechanism.

l.Figure 3 is a detail view of the cam, nger-plate, and cam-plates.

parts.

-' lhe. object of this invention is to provide animproved motion of the fingers of the feed-attachment for rotary cutters for cutting paper, pasteboard, sheetmetal, India rubber, 85e., wherebythe said fingers are actuated to move forward, in feeding the material to the machine, in a horizontal manner-and at the completion of the forward movementwithdraw below the surface of thefeed-board or apron, audreturn beneath the said board, to again rise and repeat the feedingmovement, thus leavingroom (during their backward movement beneath the feed-board) to place o n the apron the succeeding quantityof material which is to be fed up to the operating-mechanism of the machine.

In the drawings- O C O is the general frame Aof a' machine, taken to illustrate my feed-attachment.'

The said machine has a cutter-roller, A, and counter-roller, B, on each end of which a belt, I, runs, thus receiving motion to drive :the feed-attachment.

Eis the feed-board or apron, aiiixed to the extensions G of the frame G C C.

D are plates, between the extensions G, and affixed underneath the apron E..

These plates'furnish bearings for the shafts of the 'feed-mechanism. i

, 4The belts I run on pulleys, H, on the short shaits a,

the said pulleys being between theplates Dv and the extensions G.

The shafts'a extend through the plates D, and their inner ends are provided with cranks, d. The said cr. nks are connected by a rod, b,'o1i which the connecting-rods, j, -work loosely, as the cranks revolve.

The opposite ends of the rods f are afiixed on a rod, e, the ends of which latter are reduced, and work freely `in steps 'or sockets in the sliding uprights g.

These uprights are-provided with projectionsp, which' slide with easy Contactin grooves,'o, in the plates D, as shown.

By this train of mechanism, the uprights g are m'oved t0 and fro, asthe roller B is' turned.

'The feed-fingers'i project up through slots, k, iii the 'feed-board E.

These' ingersgrise of which is aixe'd to a vibrating guide-plate, Ah-,which latter is pivoted to the uprights g, as shown.

The lower edge of each guide-plate rests on a cam, n, 'on the shaft a, (see tig. 3,) and the said cam is so arranged, w-ith reference to -the to-and-fro movement of the guide-plate, that it will be uppermost when the guide-plate is moving toward the cutter-roller A, and

underneath when the same is receding from the said roller, so that the fingers 'i will' be protruded upward Athrough the slots, just as they begin to move forward,V

and so held until. the forward movement is completed, when the cam, having then passed from' contact with the guide-plate 7:,'permits the latterto rest on the Similar letters of reference indicate corresponding shaft a, or reduced part of thel eam, and` the guideplate thus withdraws the fingers from the slots.

The shaft-a then supports the guide-plate dining the backward stroke, when the cam n again encounters the guide-plate, and raises it, asbefore. R

Whatever is laid on the feed-board, in fi'ontof the fingers, (as shown in red color,) will thus be actuated up to the cutter-roller, or other prehensive part ofthe mechanism of a machine to which my invent-ion is ait-:

tached; but in orderto obviate the necessity of adjusting the material to befed up by the fingers, against the latter, I employ a guide-board, q, having slots which merge into the slots of the apron, as shown.

The material is placed against this guide-board while the fin gers are passing backward underneath the apron,

and the fingers, in rising, emerge' from the slots behind -the material placedagainst the guide-board.

By means of this feature, no especial care is necesranged to operate as here'in described, for the purpose Specified.-

2. 'The guide-board g, substantiallyas described, in

combination with the apron E, fingers i, and their-actuating-mechanism, all substantially as'describ'ed,'for the purpose set forth.

3. The guide-plate h, carrying the fingers t', operated,

as described, bythe cam n, upon the shaft a, through the Vmedium of the lcrank (l, connecting-rod f, shaft, e,

and upright g, sliding in the grooved plate D, as herein` described, for the purpose specified.
